Abstract

An efficient methodology to access a library of 1,2,4,5-tetrasubstituted imidazoles from a broad range of amidines and α,β-unsaturated aldehydes/ketones via a C(sp2)-H amination has been developed. This method represents a new and simple way to prepare highly substituted imidazoles from easily available starting materials, inexpensive catalysts, and with good functional group tolerance in good to excellent yields.

Abstract

An efficient method for the synthesis of 3-alkylated indoles is described. The oxidative cross-coupling reaction of diphenylmethane derivatives with indoles at the C-3 position was achieved employing the N,N-dimethylcarbamoyl moiety as an auxiliary group in the presence of iron(II) chloride (FeCl2) and 2,3-dichloro-5,6-dicyanoquinone (DDQ).
